Specification of Letters Patent.

Application filed November 21, 19 17. Serial No. 203,162.

To all whom it may concern:

Be it known that I, ROBERT CLoUoH CLARK, of the city of Winnipeg, in-the Province of Manitoba, Canada, have invented certain new and useful Improvements in Roofing-Clips, of which the following is the specification.

The invention relates to improvements in roofing clips and the principal object of the sheets.

3 represents an enlarged lan view i of a ragmentary portion of one o the clips.

Fig. erepresents a side view of the same.

Fig. 5 representsa plan view of a modified construction of the clip. 7

Fig. 6 represents. a side view of another I modified construction of the clip.

In the drawing like characters of' reference indicate corresponding parts in the several figures. V

1 represents the usual roof board on which the roofing sheets 2 are ap lied with the lower edges of the upper s sets overlying the upper edges of the lower sheets and with the ends of the adjacent sheets butted together.

In order to make the invention clear I may say that these roofing sheets are customarily formed from a rubber and tar composition and are fastened to the roof by nailing.

My clip, utilized in fastening sheets is now described.

It comprises a length of wire 3 fitted at intervals throughout its length with loops 4 adapted to receive the nails and having the extremities terminating in end'coils at 5 and 6. At this point I wish it to be noticed that the coils and loops all turn in the same direction and are contained in the same plane so that when the strip is applied on the roof the coils and loops all face tip-- wardly toward the peak of the roof or in a direction away from the edge of the sheet on which they are applied. These long strips are laid on the overlapped edges of the sheeting a short distance above the lower edge of the top or overlying sheet and they are nailed to the roof by-nails 7 inserted at the loops and having heads sufliciently large to cover the opening in the loops when the nails are driven home. utilizing these strips to have them long enough so that the coiled ends thereof lie at the corners of the applied sheeting, as the coils give increased bearing surface to hold the corners of the sheeting from turnmg up and they also prevent the possibility of the sheeting being punctured by the strips.

Obviouslywhen the clip has been applied, it holds the edge of the sheeting tightly down preventing curling at the edge and the consequent damaging eii'ects of wind and rain. Further it will be seen that the loops It is desirable in etween the clips can be applied at the ends of the sheetsame direction and having the extremities 10 ing as shown at 8 and 9 in Fig. 1. thereof terminating in coiled ends.
